Detailed description:

The carbon fiber furnace atmosphere box furnace uses 1800 molybdenum wire as the heating element, adopts a double-layer shell structure and a 40-stage program temperature control system of Shimadden, phase-shifting trigger, SCR control, the furnace uses carbon fiber materials, double-layer furnace shell The room is equipped with an air-cooled system, which can quickly rise and fall in temperature. It adopts the integral sealing of the shell, the cover plate and the furnace door are sealed with silicon O-rings. The furnace door is also equipped with a water-cooling system. There are burners at the air inlet and outlet of the washing furnace, which can be pre-evacuated and can pass hydrogen, argon, ammonia decomposition, hydrogen and argon mixed gas and other gases. The furnace has a balanced temperature field, low surface temperature, and rapid temperature rise and fall. , Energy saving and other advantages, it is an ideal product for universities, scientific research institutes, industrial and mining enterprises for atmosphere protection sintering and atmosphere reduction.

• It can be connected to the computer. (Need extra cost for this optional parts)                                                                                              The furnace is equipped with communication interface and software, which can directly control the various parameters of the furnace through the computer, and can observe the PV and SV temperature values on the furnace and the operation of the instrument from the computer. The actual temperature rise curve of the furnace will be drawn by the computer in real time. And it can save the temperature data at each moment, and it can be recalled at any time.                             
• Cover opening protection system: The furnace is equipped with a travel switch, which will automatically cut off the power when the furnace cover is opened, effectively ensuring the safety of users.
• Sealing system: The furnace top cover and furnace door (other places have been welded) are both extruded and sealed with silicone O-rings, which are convenient to remove and can be removed repeatedly. The air tightness is good, and the pointer of the pressure gauge can be guaranteed for 8 hours without deflection.
• Furnace material: Use carbon fiber material, no powder, good insulation performance, high reflectivity, balanced temperature field, strong resistance to thermal expansion and contraction, because carbon fiber is reducible, the most obvious advantage of this furnace compared to alumina fiber furnace is :
  1. The carbon fiber furnace has extremely low oxygen content, and no oxygen-containing gas will be released at high temperatures;
  The alumina furnace has high oxygen content and releases oxygen-containing gas at high temperature.
  2. The carbon fiber furnace has less water content, and the vacuum degree is high when vacuuming, which can reach 0.008Pa;
  The alumina fiber furnace has high water content, and the water is not easy to clean up, and the vacuum degree is low when vacuuming.
  3. The carbon fiber furnace is resistant to acid and alkali;
  The alumina fiber furnace has poor resistance to acid and alkali.
  4. The carbon fiber furnace has strong resistance to various erosions and can resist carbon erosion very well. It is an ideal product for making silicon carbide materials and carbide materials;
  The alumina fiber hearth is easily corroded by carbon.
• Heating element: The heating element (1800 type molybdenum wire) is hung on both sides of the furnace through the hanging plate (rather than in the middle of the material that penetrates the furnace), which improves the thermal efficiency and makes it more convenient to replace the heating element;
• Leakage protection function: The furnace is equipped with a leakage air switch, which automatically cuts off the power when the furnace body leaks to ensure the safety of use.
• Air outlet valve: The air outlet valve is a one-way valve, and the gas can only flow out and not flow back.

OPTIONAL ACCESSORIES:

• Optional 1.) Explosion-proof system: Explosion-proof system is composed of solenoid valve, microcomputer, pressure display and transmitter, 24V power supply, AC contactor, etc. The pressure in the furnace is converted into an electric signal through the pressure display and transmitter and transmitted to the microcomputer. The microcomputer compares with the set value, and then gives a signal to control the AC contactor, thereby controlling the opening and closing of the solenoid valve. When the pressure in the furnace is greater than the allowable pressure set by us, the solenoid valve will open immediately to play an anti-explosion effect. We have installed an air outlet pipe on the solenoid valve, and the user can connect the pipe to exhaust the gas outdoors, and the explosion-proof valve is one-way The valve can only exhaust gas, not return flow, which effectively guarantees the safety of the furnace.
  The explosion-proof system has many advantages:
  (1) Reusability: The solenoid valve opens when the pressure is greater than the set value, and closes when the pressure is lower than the set value. Unlike a mechanical riot control device, it cannot be used once it bursts.
  (2) The setting value is adjustable: the user can adjust the opening pressure of the solenoid valve through the microcomputer as needed.
  (3) The explosion-proof point is very sensitive: because the microcomputer and electric signal are used, it will detonate immediately when the pressure reaches the explosion-proof point.
  (4) Explosion-proof system safety: no fragments fly out during detonation. (If a mechanical type is used, the glass may fly out).
  (5) The explosion-proof system has good stability: because of the use of microcomputers and solenoid valves, it will detonate at our set point, and users can test it. Unlike the mechanical type that cannot be tested, there are many differences in whether the explosion-proof point will open or not. Certainty.
• Optional 2.) Under-pressure alarm system: When the furnace pressure is lower than a standard atmospheric pressure (the pressure value is adjustable), the electric furnace will automatically alarm to indicate that the intake air flow is insufficient, and can decide whether to cut off the heating circuit according to the needs of customers power supply.
• Optional 3.) Gas supply system: The furnace can be equipped with 2 or 3 float flow meters, which can control the gas flow rate. Each inlet has a stainless steel valve. You can choose one of them or Several channels are used to adjust the gas. The gas enters the gas mixing tank after passing through the flow meter, and then enters the furnace body in 3 channels, so that the gas can flow into the furnace body evenly.
• Optional 4.) Vacuum system: The atmosphere box furnace can be pre-evacuated to speed up the cleaning of the air in the furnace.
• Optional 5.) Combustion device: The furnace can be equipped with a hydrogen burner to burn the gas discharged from the furnace.
• Optional 6.) Water cooling system: The furnace is equipped with a water cooler, which can automatically cool the road entrance.
